short way to earn money 0

Few days ago a member of yahoo answer group asked a question that how to earn huge amount of money in very short time. I replied him to do some illigal work ya invest in share market
people are comming to share market day by day.But many of them have no sufficient knowledge of market.So they often huge amount of loss.
But share market is so easy.So take it as a easy matter.
Suppose someone give you rs 1000000000 to do some business.Then you should think what business is suitable to you and also you should think the future of this business.
First think about some business,like.
1) real sector
2) constraction
3) banking
4) insurance
5) power sector
6) cement
7)retail business
8)home applicants
9)telecommunication
10)IT
11)home applicants

But in real you have not so big amount of money.Just you have 50000rs.So you can think to buy the shares of these company.But buy these shares who are in leading power.
